I'm having trouble finding the LCD- lowest common denominator and having trouble solving it. 4/63+1/45=
...
63 = 3*3*7
...
45= 3*3*5
..
What are the common factors in the two numbers 2 Threes
3 & 3
what are the other non common factors 5 & 7
so
LCD = common factors * noncommon factors
LCD = 3*3 * 5*7=315
so LCD = 315
..

multiply by LCD
